There are other ways to get off-line access to online resources such as On the Road.
Using Firefox, there is an Add-on called 'Scrapbook" and this allows you to save a web page and store it on your computer and access it via a list similar to bookmarks.
It also allows you to save an entire web site down as many layers of links as you want to go. Can be huge files of course but the download process is automatic and then you can browse that site off-line just as if it was on-line. Obviously it is a snapshot at that moment but as has been pointed out, these sites don't change month to month let alone daily
iOverlander, with a bit of help from us, would be hard to beat though
OK, OK, no more spruiking from me.
